Water Demand, Supply and Distribution Necessity for water supply? Necessity for water supply?
1) Human being needs water to survive:
drinking water: 3 10 [l/C*d]
2) People need water on health reasons:
drinking water, preparing food, wash up dishes, body care, washing of clothes, cleaning 15 25 [l/C*d]
3) People are claiming water with rising living standard:
2) PLUS Flushing toilets: 40 60 [l/C*d]
2) PLUS Flushing toilets, shower, bath: 80 [l/C*d]
2) PLUS 3) PLUS irrigation of gardens,
swimming pools, car washing: 100 600 [l/C*d]

Water Demand, Supply and Distribution Necessity for water supply? Necessity for safe water supply?
Impurities found in water Constituents of health significance:
Microorganisms Chemical substituents
Aesthetic parameters Technical parameters
Sources for impurities Source Treatment Transmission and storage Distribution
Basic requirements for drinking water Free from pathogenic organisms No compounds with negative effect on human health Clear, not salty, no bad taste or smell Not causing corrosion or encrustation of water supply system

Water Demand, Supply and Distribution
Goal of Centralized Water Supply Systems:
Safe supply of all consumers round the clock with highest quality,
suitable quantity and pressure, low costs and minimized impact on
natural water cycle
Advantages:
Hygiene Safeguard of Supply Comfort Economy Socio-economic development Ecology

Influence on natural water cycle
Global figures:
World oceans evaporation 425,000 km/a
World oceans precipitation 385,000 km/a
Land evaporation 71,000 km/a
Land precipitation 111,000 km/a
Land runoff 71,000 km/a
Global drinking water demand:

Water Supply today
Germany:
Small areas suffering water shortage long distance supply
Centralized water supply systems, Connected > 99 %
Safe supply of all consumers round the clock with highest quality, suitable quantity and pressure, low costs and minimized impact
on natural water cycle
Worldwide:
Mega-Cities in areas suffering water shortage
~ 50 % of worlds population has not enough drinking water
1.1 Billion people without access to well organized Water Supply
.. 5 Million people yearly die as a result of bad drinking water
or lack of drinking water (60 % children)

Homework
3 Questions at the end of each chapter:
1) Why is it necessary to have a safe 24/7 water supply?
2) Why only the last part of CWSS downpipe and distribution net- has to be dimensionend on base of Qhmax
whereas in others parts from intake till EST- we are free to dimension (and operate) on base of Qdmax ?
3) Check your basic knowledge in hydraulics for
understanding of water supply systems: Terms like
Hydraulic grade line, velocity head, pressure head etc.,
must be well known..
